Patent CA-1078815-A (CA)
Inventor: DUMMER ROBERT E
IPC: E21B7/02
Filed: 1978-06-01
Granted: 1980-06-03
Abstract: ABSTRACT OF THE DISCLOSURE A control is disclosed for inhibiting the tilting of an earth drilling machine that is supported on hydraulic jacks. A hydraulic downfeed motor for the drill string is operated by a control that has pressure responsive switches connected to the hydraulic jacks, and in the event the drilling machine starts to rise upwardly during drilling one of the pressure responsive switches will operate to shut off fluid pressure to the downfeed motor and to entrap fluid within the motor.          The entrapment of fluid in the motor maintains a drilling pressure that permits drilling to continue with a drilling force that will not allow the machine to rise upwardly on the supporting jacks.

Title: Evaporator assembly
Inventor: RICHARDSON DAVID W
IPC: F25D11/00
Filed: 1978-06-15
Granted: 1982-02-02
Abstract: ABSTRACT OF THE DISCLOSURE An evaporator assembly for a heat transfer unit comprises a sealed thermally conductive container and a duct mounted in the container.  Channels are formed between the walls of the duct and those of the container and thermal transfer fins are attached to the inside surfaces of the walls of the container and located in the channels.  An evaporator extends transversely across the width of the duct and a defrosting heater bank is located downstream from the evaporator in the duct.   Suitable fans and a drive motor are mounted at one end of the duct to circulate air or other gas through or across the eva-porator, through the duct, and through the channels. During use of the assembly, heat is transferred from the container walls and the fins to the circulating air and the heat is then extracted from the air or gas by thermal transfer through the evaporator.  The assembly provides a buffer between the heat source and the evaporator in order that the evaporator may operate in a near moisture free environment.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a portable progressive and intermittent traction machine, that is, to an electrically powered device for providing traction to a patient.  In order to provide intermittent traction, a number of portable intermittent traction machines have been designed, each of which including a cord and means for applying a force thereto for an amount of time set by a master.  However, it is often desirable to be able to progressively increase the force and to hold the force at each progressive level for a period of time before the force is again increased.  Furthermore, in many cases, it is desirable to have the force alternate between a high and low, non-zero force level.  A machine for operating in this manner has been unavailable hereto-fore.  According to the present invention, there is provided a portable traction machine which solves these problems in a manner unknown heretofore.  With the present machine, any desired traction force can be applied statically or intermittently, for a time set on a master timer.  In the case of intermittent traction, the hold time and the rest time are independently adjust-able.  Also in the case of intermittent traction, the maximum force level and the minimum force level are independently adjustable and the minimum force level can be anything between the maximum force level and zero. A visual indication of the traction force is available. Furthermore, the traction force may be applied progres-sively, and the time of each cycle can be adjusted.

Abstract: DIE PRESS HAVING SELECTIVELY VARIABLE                 DIE ACCESS CLEARANCE     Abstract of the Disclosure:        A press has at least one reciprocal ram securing a die movable to and from an opposing die, the ram normally spacing the dies apart with a predetermined normal clearance.  The die is retained in the ram assembly with at least one tensioned longitudinal bolt which bolt also normally compresses a spacer member, the bolt having longitudinal stretch-ing means selectively actionable for longitudinally stretching the bolt without otherwise affecting bolt adjustment to relieve compression on the spacer member and permit selective transverse removal of the spacer member   When greater than normal die access clearance is required, the bolt is stretched, the spacer member removed and the ram longitudinally shortened in length for the increased clearance.          Ram relengthening, spacer member replacement and an ultimate relieving of bolt stretching reassembles the ram in exact original normal form with the exact same bolt tensioning.  A multiplicity of bolts and spacer members all identically operable may be used in a particular ram assembly depending on the requirements and with appropriate controls for automatic sequential operation thereof.

During liquid fuel operation incoming air lowers the pressure in the chamber sufficiently so that the inner plate automatically moves away from the adapter plate to provide an unobstructed air only path to the engine air intake.
